Best prog bassist?

I searched the whole forum for this topic, but I could not find it, so I decided to make it myself. So, who do you think deserves the title of best progressive rock bass guitarist?

I have a few favourites myself, but the one and only Gary Thain of Uriah Heep has to be the one I am most fond of. He is one of the few (Pink Floyd-reference, heh) bassists who (for me) made the instrument interesting and fun to listen to. His bass lines are creative and fits perfectly in the music and very often steals the show, probably because he was the best musician in Heep before his gruesome death.

Other favourites include:

John Glascock & Jeffrey Hammond-Hammond (Jethro Tull) - Unfortunately, I have only listened to two albums he played on ("Songs From the Wood" and "Heavy Horses"), but I adore both of these albums and his skills are amazing, very precise and technically brilliant. R.I.P.
I like Hammond-Hammond, because of the Aqualung-album, a great bassist.

Roger Waters (Pink Floyd) - While he has never been a brilliant musician, Waters was the brain behind the middle era of Pink Floyd, but certainly had some nice input to the music as well. His best known bass line has to be "Money", very simple and very catchy, but why not? "Aqualung" has also a very simple riff, but the song is brilliant. He is also one of the very few bassists who has continued playing and he is even better at this age (67 this year!). But for me, my favourite musical work of Waters has to be the entire "Animals" album from 1977. He really shines on this, both lyrically and musically and really did it his own way ("Pigs" and "Dogs" f.example). Without checking a list of Pink Floyd-songs, "Interstellar Overdrive" and "One of These Days" also pops up when I am thinking of Waters. HIGHLY underrated.

Colin Bass (Camel) & Doug Ferguson (Camel) - Also one of the ones I have listened to too little. I love "Nude" and his playing is just as good as his soothing voice. Early Camel also includes Doug Ferguson and although I am not overwhelmed by his abilities, he really delivered on "Snow Goose" and "Moonmadness".

Guy Pratt (Pink Floyd, David Gilmour) - As well as being a jolly hilarious chap, Pratt really filled the shoes of Waters musical input from the "Momentary Lapse of Reason" - tour and onwards. Very talented bassist who has also played with David Gilmour after the disbandment of Pink Floyd.

So let me hear your opinions!

Hugh Hopper (Soft Machine and many other bands), Richard Sinclair (Caravan, Hatfield and the North, Camel), Chris Squire (Yes) and Jannik Top (Magma).

Tony Levin. Although he's a stickist at heart.

Chris Squire, John Deacon and Paul McCartney. I love their melodic bass-lines. i.e. Roundabout, Close to the Edge, You're My Best Friend, or almost anything by The Beatles.

Lol OP. Aqualung was Jethro Tull, not Pink Floyd. And on Pigs (Three Different Ones), Gilmour played bass. Not Waters.

As for me, I'd have to say Chris Squire of Yes.

Nick Beggs! He was GREAT during the last tour with Steve Hackett!

Richard Sinclair, for me. I like his creative style.
And, of course, Ray Shulman, from Gentle Giant.

Geddy Lee
Chris Squire
Roger Waters
Greg Lake (not the best bassist, but he is an excellent singer)

John wetton, his "right in your face" style amazes me every time.

Chris Squire and Justin Chancellor

Listen to "Improvisation - Ekseption" and you'll hear a wonderful groovy bass solo by Cor Dekker.

John Glascock...
